On 10 August 2017, Swedish freelance journalist Kim Wall boarded the midget submarine UC3 Nautilus with the intent of interviewing its owner, entrepreneur Peter Madsen.
She was reported missing after the submarine failed to return to Refshaleøen, Copenhagen.
The submarine was found sunken the following morning and Madsen was arrested upon being rescued from the water.
Between 21 August and 29 November, Wall's dismembered body parts were found in different locations around the area.
Charged with her murder, Madsen was convicted and sentenced to life imprisonment on 25 April 2018 by Copenhagen City Court following a widely publicised trial.
The case is also known in Denmark as Ubådssagen (transl.?"The submarine case").
